Abstract

The present invention relates to a clock having an electronic type or electronic mechanical type adjustment function. The adjustment (SET mode) of the operation mode of the clock is not selected by a special operation mode convertor, and thus, the expense of a switch structure is saved and the generation possibility of a misadjustment deviation is reduced. Temporary conversion to the SET mode is realized by simultaneously pressing PLUS and MINUS key switches (18, 20) of a reconnection circuit of a manual counter, and then, one of the PLUS and MINUS key switches (18, 20) is respectively operated to change the actual display content of a register in order to realize positive direction accumulation or reverse direction accumulation. The clock also comprises the function of displaying the actual value and the preset value of a ringing time point.

Description

Ring the clock of the time display that makes a noise with convertible time display and particularly numeral

The present invention relates to a kind of clock (10), have time zone (13) and a mode of operation translation circuit by the display device (14) of display register (24) control, be used under the adjustment mode according to PLUS or MINUS keyswitch (18,20) manually operated ratio deposits the pulsed feeding that adds up in display register (24).

This clock is commercial general, according to this clock of standard three switches (generally be the regularly time point of quarter-bell of harmonizing, but also can be engaged in the time zone displacement of time display) that are used for manual adjustment is housed.It one of in these switches a transducer electronics or machinery, the register of the temporal information that the moment of utilizing it will write down running status shows is transformed into adjustment mode or locator meams, and the pulse repetition rate that individual pulse or the inner pulse train that has produced-preferably have is progressively increased by other two switches-with up to now content of registers addition or subtract each other.Therefore in adjusting function, can change some ring time that provides in the time range predetermined and, or showing T.T. of clock is replaced into another time zone in display device.

Problem in actual the use is, any swing or unintentional action under every kind of input mode all make switch connection, thereby may change register information at that time, although the end user did not have careful these actions of noting at that time at all, therefore the end user may not know the demonstration that should remember at that time, so be difficult to return the original correct demonstration time again.

From this operative technique problem as seen, there is defective in the ordinary clock and watch device that has three adjustment switches, it requires expensive high-precision electronic mechanical devices, and need be assemblied in the shell aperture, the expense that this also need add, this causes the manufacturing cost height, considers the principle of design of the clock of at present popular cheapness, and this is a very important weak point.

The objective of the invention is from this technical matters, a kind of like this clock is provided, it is reliable operation not only, and is convenient to economical and adjustment easily.

Task of the present invention mainly is to adopt the feature of the characteristic of main claim to realize, promptly the method for operation conversion to the mode of adjustment is to realize by operating two keyswitches (18,20) simultaneously.

The present invention has given up adjustment (SET) transducer that separates, and from the method for operation displacement that running status changes to the adjustment state is by the moving of two remaining positioning switches itself, and operates to moment the transition of these two switches realizations to the adjustment mode at least overlappingly simultaneously.So, keep second keyswitch motionless, and the pulse that in register, will add up by the input of another switch; Or after realize adjusting (SET) mode these two keyswitches of operation separately, adopt which kind of scheme, depend on the forward or negative sense carries out of adding up of content of registers.When crossing preset time these two keyswitches all no longer move at interval, this clock can turn back to the method for operation from adjusting (SET) mode automatically.Thereby determined the following fact, adjusted (SET) state or positioning trip state and can not obscure and produce mistake mutually, side by side operated consciously and could replace because must adjust button to two; And omitted the interior extra switch of prior art clock, obviously reduced the required expense of assembly, installation and adjustment.

Electronic mechanical or electronic type regularly forecast with the electronic mechanical of one preferably digital-some ring time moment of harmonizing or electronic console for having, its time point adjustment can start by operating two control buttons simultaneously, and then carries out optionally button operation and finish.Also can change the actual displayed situation of clock with the same manner.According to another aspect of the present invention, this clock has the receiver of a collection dress, it at least between or provide airborne and be used for the absolute time of automatically control and in case of necessity the moment time showing of clock proofreaied and correct, thereby utilize two key operations of method of operation conversion and selectivity single key stroke subsequently, realization is carried out the time range adjustment to the demonstration time deviation that is occurred with scope received At All Other Times temporal information comparison.For in this time range displacement mistake does not take place, and in order to realize timing alarm adjustment or the adjustment of the time range time difference on demand by same selectivity button operation, suggestion is at first pressed another button when just replacing adjustment (SET) state, preferably adopt nap (Snooze) button that was equipped with originally in the common ring alarm clock.

Inquiry for aforementioned logic control (button operation) can utilize gate circuit to realize.Less expensive reasonably is to adopt at the logical block that resolves of processor inside to realize the described inquiry of replying, sort processor is just to have originally in the wireless electroclock device, so that the time telegram of demodulation is determined (verfixieren) and proofreaied and correct actual time showing in case of necessity.

Further distortion of the present invention and formation and other feature and advantage are embodied in the theme of dependent claims, also be described in the content of summary, below in conjunction with description of drawings the preferred embodiments of the present invention, this accompanying drawing is the general principal view of clock device of the present invention, and its electric connecting member is represented with circuit block diagram.

Clock 10 removes cover plate in front view, only provide outer contour, and this clock is a kind of alarm clock, can be the clock 10 that pure digi-tal shows, or is simulation one digital mixed display formula as shown in the figure.Movable pointer 11 is housed before dial 12, also has the digital display device 14 that can replace simultaneously between the temporal information that derives, it can be used for displaying calendar, and under the situation of alarm clock 10, each ring can show the time of giving the correct time.The time range 13 of display 14 can be by manually or automatically realizing conversion and show, for example actual date (monthly and day) or other information (as the instantaneous actual hour, promptly because the fast moving that the conversion of manual release time range produces pointer 11).

The independent information segmenting 15 of display is used for special demonstration, when circuit working is given the correct time in ring, adopt an electronics in this segmentation, to show incessantly with regard to bell character 17 of parallel operation 16 controls, otherwise, when the ring circuit that gives the correct time is in when the described locator meams, this segmentation flicker shows, and breaks away from when carrying out (disconnections) when the ring circuit that gives the correct time, and 15 of above-mentioned segmentations do not have demonstration.

If clock 10 has between one or the receiver 21 of ground time of reception telegram from radio propagation, 15 of this information segmentings also comprise a digital received viewing area 19, its display digit information, when real time demonstration (the manual or time that is subjected to is controlled) is controlled and is needed to proofread and correct in 21 implementations to receiver, this viewing area is connected, and need not to receive telegram lock in time.In general, the temporary transient connection of receiver 21 causes continue receiving available time telegram, therefore receives viewing area 19 and shows " 0-0 " values, when the demonstration of these normal conditions is not switched on, when avoiding some stimulation (Irritationen), receive value that viewing area 19 shows greater than 0.When the control real time shows and to make pointer move quickly into an angle position after the correction when having an error with respect to the information from the time telegram, afterwards, by the pierce circuit of inside again driving time keep function.Reflection can temporarily be shown in the independent time range 13 to the hour information in the time interval of correct pointer position transition.

For the display 14 of clock 10 being converted to locator meams or adjustment (SET) mode by transducer 16, must operate two keyswitches 18 and 20 in short-term, they all are connected with logic gate 23 (UND) with one.Also have a display register 24, its instantaneous value is presented on the time range 13 of display 14, and display register 24 increases the sequential circuit of content of registers according to pulse input (can see) forward increase or negative sense in time range 13 by transducer 16.

Display on the time range 13 is a kind of normal time showing, and the autonomous quartz crystal Stabilization Frequency Pulsed drives that is shown by numeral is in the time of can realizing manual school or the time range conversion on this display; Perhaps will put predetermined value ring time deposits in the display register 24, again it is compared by the actual hour value in a comparer 25 and the time regulator 26 when receiver 21 schools by a wireless electroclock 10 (but), so that under situation about overlapping, control signal generator 27 work optics and/or acoustics, the motor 28 that the driving pointer of not drawing in detail among the figure in addition 11 moves, by time regulator 26 controls, drive pointer action by gearing 29, on the dial 12 of clock 10, also have simulated time to show, just as shown in FIG..In this case, the magnetic antenna 29 of the supply receiver 21 relevant with (stepping) motor 28 should be installed like this or motor is started intermittently, so that the electro-magnetic feedback that is produced by the motor operation is disturbed the function that the receiver input circuit can not take place and influence.

Display register 24 will be thus (by electronic converter 16), is used to receive continuous impulse, and its actual accumulation result is presented in the time range 13, two the location keyswitches 18 and 20 operate simultaneously, this operation control change device 16 with logic gate 23.

Can in transducer 16, install a holding circuit 30 additional, as long as one of switch 18 or 20 keep pinning, and another numeral of just carrying out the little unit of display (for example minute) by button operation increases or numeral reduces timing, and this holding circuit just maintenance opens circuit to possible input.When two switches 18,20 did not continue to operate, this holding circuit discharged.

If without such scheme, also can make this holding circuit 30 have a commutation and postpone.Utilize AND gate circuit 23 and holding circuit 30 to make display register 24 be in the preparation accepting state, two keyswitch 18,20 operations overlappingly in time; Follow or operation push-button switch 18, realize the digital forward cumulative process of register 24, perhaps operation push-button switch 20 is realized digital negative sense cumulative process, and need not keep manually pinning another switch.After through the time interval trace of predetermined circuit engineering or programming technique during without any button operation, similar behind the last EO of one of keyswitch 18 or 20 10 seconds, any input possibility of holding circuit 30 blocking-up display registers 24.

After (SET) mode of adjustment finished, display 14 showed actual running status again.This means, when disconnecting ringer function, show date on the time range 13.Connect this ringer function, needn't operate two keyswitches 18 simultaneously, 20, but or operation push-button switch 18 only, or only operation push-button switch 20 through a minimum interval trace (for example only 3 seconds kind), this realizes that by continuing to press described switch the result demonstrates bell character 17.Under this duty, two keyswitches 18 of selectivity operation or one of 20 realize that time range 13 displaying contents are in the given conversion of ring time between the point of actual date and moment with (for example keeping the time below 3 seconds) by in short-term.Signal generator 27 should be launched its ring time signal immediately, selectivity is operated one of two keyswitches 18 or 20 in short-term then, ringdown is interrupted, will after 24 hours, start (this preparation done state can be shown as by the persistence of bell character 17 known to the end user) so this ring is given the correct time.If operate certain keyswitch for a long time separately, convertible current given ring prepares to finish the time of attitude, also can replace " connection " state from " cut-out " state, otherwise or also can; Under dissengaged positions, the vibration symbols 17 in the information segmenting of display 14 15 do not show, and become on the time range 13 and show date.

Alarm clock 10 also is furnished with a nap (Snooze) button 31 traditionally.When alarm clock runs to when putting predetermined ring time, the ringdown emission, this moment, operation push-button 31 was then temporarily restrained sending of this ringdown, through discharging this signal (repetition ringer function) after the time interval of known about a few minutes again.In addition, number of ports letter disk illumination functions in short-term also.

Funtcional relationship as the demonstration of embodiment circuit diagram, when keeping nap (Snooze) button 31 to be in adjustment (SET) mode, in the operation push-button switch 18 or 20 any, then minimum convertible chronomere in register 24 or 26 the content (be generally minute) does not change, just realize with time range conversion whole accordingly (or the half) hour (hour) variation.For avoiding time range when displacement to produce mistake, also can discharge the possibility of conversion consciously, this can be in adding (PLUS) and subtracting (MINUS) keyswitch 18 and 20 produce excitation (as ring adjustment mode) of adjustment mode by operation simultaneously; Then when keeping nap (Snooze) button 31, operation push-button switch 18 and one of 20 obtains the required time range conversion.Holding circuit 30 is ended this adjustment (SET) mode once more, and prerequisite is no longer arbitrary keyswitch 18,20 to be operated after the trace at interval through a preset time.Thereby the content of time regulator 26 changes to another time range exactly.The repeatedly rotation of the minute hand that causes corresponding to the time range displacement needs to continue a definite time at every turn.Therefore as being subjected to radio controlled time adjustment process, on time range 13, demonstrate from now on effectively hour number at least.When pointer 11 has changed the angle position of new and new time range coupling over to, return to then on time range 13 that the date shows or show ring time.
